An alleged RAND Corporation leaked memo which surfaced in early July 2014 provides three stages for the conduct of a military operation in eastern Ukraine. Phase one calls for total isolation of the target. (Background: RAND Corporation Phase One Initiated?, Ersjdamoo’s Blog entry of July 25, 2014.)
In other words, in phase one, a curtain is to be drawn around the target, preventing the world from seeing what is to happen in the phase two “Mop-up”.
Coincident to the emergence of the purported RAND Corporation memo, Willy Wimmer, the former Vice President of the Parliamentary Assembly of the Organization for Security and Cooperation in Europe (OSCE), had this to say about reporters being killed in eastern Ukraine:
The killing of journalists is an organized effort to continue with the control of the mainstream media in the West.
For some weeks the only chance to get a fair picture of the situation in Ukraine on TV has been Russia Today, France 24 or Al Jazeera.
When you kill Russian journalists, you see efforts to maintain the dominance in propaganda. It is not a coincidence that journalists are killed. It is a combined effort to do so. And, therefore, it is an attack on democracy, that’s for sure. 
The killing of the Russian journalists could be part of the RAND Corporation “phase one” curtain.
In yesterday’s blog entry, Russia Mobilizes Troops, it was surmised that Russia was about to launch its own humanitarian intervention in eastern Ukraine, to protect the lives of non-combatants in Lugansk (also called “Luhansk”). Today, August 6, 2014, it is reported that Russia has called for an international humanitarian mission to be launched. 
“Russia called for an emergency UN Security Council session on the humanitarian situation in Ukraine on Tuesday.” 
I believe Russia will intervene with or without United Nations approval. (And UN approval for a humanitarian mission would go against the purported RAND phase one, by pulling aside the curtain. So such approval seems likely to be blocked by the U.S.) President Vladimir Putin of Russia had earlier promised to protect the Russian-speaking people of eastern Ukraine. He is honor bound to do so, given the present humanitarian catastrophe in Lugansk/Luhansk. It would be better to go in with UN approval, but Putin is honor bound to act, whatever the case.
There is a strange similarity here to the situation 100 years ago, when Russia was honor bound to protect Serbia. On June 28, 1914, Archduke Franz Ferdinand was assassinated at the hands of a Serbian nationalist. About a week later, Austria-Hungary received a pledge from Germany, known as the “blank cheque,” for any support necessary to deal with Serbia. But on July 21, Russia, an ally of Serbia, warned Austria-Hungary against taking action against the Balkan state. Nonetheless, Austria-Hungary ratcheted up the pressure, and finally declared war July 28. On July 31, Russia mobilized its troops, and the next day Germany declared war on Russia. Within days France, Belgium and Britain were bought into the war. 
On August 4, 2014, the New York Times (online) had reported that the Russian air force and air defense had announced “exercises” (had mobilized) and that Russia had roughly doubled the number of its battalions near the Ukrainian border.  Today, Reuters reports that the Polish Prime Minister Donald Tusk suspects “that the threat of a direct intervention by Russia’s military in Ukraine has risen over the last couple of days.”  Also today, CNBC reports that “European shares fell sharply in morning trade on Wednesday with concerns that tensions between Russia and Ukraine could escalate further.”
